Application tied Maa 6.1899,

To all whom t mrtg/concern:

Be it known that I, LABURTON A. GALE, of.l Malden, in the county ofMiddlesex and State of Massachusetts, have invented certain new 5 anduseful Improvements in Strap-Covering Machines, of which the followingis a specifi! lcation. This invention has relation to machines forapplying a covering to boot and shoe straps 1o with the object ofkeeping them from being soiled in the process of manufacture andhandling of the boot or shoe.

The presentinvention is an improvement on the strapcovering machineshown in Unitedv I5 States Patent No.,594,l81, granted to W. C. RandNovember 23, 1897; and it has for its object to improve the generalconstruction and operation of said machine, as willbe more fullyhereinafter described in the specificazo tion and pointed out intheclaims.

together with its monntings. Fig. 13 represents a view of the gearingfor actuating the paper-feed roll.

The same reference characters indicate the Serial No. 707,890. (Nomodel.)

The general structure and operation of the machine are briefly asfollows:

(t is the frame of the machine, mounted on a bed d', and b isthedrive-pulley, on whose shaft or stud is a pinion meshing with a gearc on a main shaft c. The webbing or strap to: be covered and cut intoboot-straps unwinds from a roll d, and after passing, when itis desiredto imprint or mark it, through a I printing mechanism it enters themainl body 6o of the machine beneath a former @,which consists of afiat-topped blade attached to a former-carrier e', which receivesvertical motion from a suitable arm engaged by a cam on the shaft c.Beyond the former c the webbing passes between feed-rollers f f,whichreceive an intermittent motion and serve to feed Ithe covered webbingforward to a severing-knife g. When the former-.e is raised, a strip hof covering material, such as paper, unwinds from a roll h', is fedforward beneath theformer and the strip of webbing which lies underneathit, a paster i deposits adhesive material on the edge of the paper, theformer e descends into a groove or path a2 cut for it 75 in the foldingbed or table co3, Fig. 4, clamping the paper and webbing beneath it, aknife j, moved by an arm j', which is engaged by a path-cam 72 on theshaft c, rises and severs a portion of the paper strip sufficient toform the cover for the webbing, and folding-plates k 7c (the plate Ztactuated by arms 7a2, oscillated by a cam on the shaft c, and the platelo actuated by arms k3, oscillated by a second cam onsaid shaft) operateto wrap the severed portion of paper over the top of the former c. Thefoldingplates are then retracted, the former e rises, and thefeed-rolls'ff, which are provided with intermeshing gears fzfs, are setin motion by the movement of a rack f4, operated by an oscillatory armf5, the said nrack meshing with a pinion f on the shaft of a gear f7,which meshes with the gear f5 on the lower feed-roll. The coveredportion of the webbing is thereby fed forward into a 95 guide or troughm, and after a predetermined length, sufficient for one boot or shoestrap, has been fed the feed-rolls stop and the knife g descends andsevers thev webbing. Mov- Y able gaging-iingers m' m', attached to rock-I oa shafts m2 m2, which have arms m3 m3 attached to their ends andconnected by a link m4, so as to move in unison, then engage the ends ofthe paper sheath or cover on the severed portion of webbing and operateto. position said cover properly on the strap. The covered strap thuspositioned is iinally forced dow n and folded between said rolls bymeans of a doubling-blade on, mounted on a rockarm m7, attached to a`rock-shaft m8, and the ends of the strap, to one of which paste orcement has been applied by mechanism hereinafter to be described, arestuck together in the passage of the strap through thc doublingrolls.

The machine as thus far described is subst-an tially the same as thatshown in the aforesaid patent to Rand, to which reference may be had fora detailed description of the action of the machine and its severalparts.

Vhen it is desired to print the name of the manufacturer, the name ofthe shoe, or such matter upon the boot-straps, the webbing d beforeentering the main body of the machine may be passed through a printingmechanism constructed as follows:

o is a suitable bed, and 0' is a standard supporting the printingmechanism and having a base o2 attached by screws o3 o3 to the bed o,said screws passing through elongated slots o4 in the base o2.

o5 is a bell-crank lever mounted between ears oG on the standard-baseand attached to a rock-shaf t o7. The said rock-shaft is journaled in abearing o8, projecting from the bed a of the main portion of themachine, and is oscillated through the medium of mechanism including anarm or crank 010, attached to the end of the shaft and connected by alink o12 with a second arm 013, mounted on a rock-shaft o, said secondarm being connected by a link 015 with a crank o16, secured on the mainshaft c. The bell-crank lever 05, by whose oscillation the parts of theprinting mechanism are operated, is keyed by a spline 017 to therock-shaft 07 and is permitted to slide thereon in the direction of thelength of the shaft.

The printing mechanism, as will be noted in Fig. 3, is mounted at adistance from the former c, so as to provide an unobstructeddrying-space S between the printing mechanism and the former, and thusleave a portion of webbing 6 exposed between said printing mechanism andthe former without contact with the mechanism of the machine, and inpractice the length of this drying-space :is made substantially equal tothe length of a severed boot-strap, so as to allow the ink deposited onthe webbing by the printing mechanism to dry before reaching thewrapping mechanism. Thus while one length of webbing to the right oltheknife g, Fig. l, is being acted upon by the wrapping mechanism thenext length (represented by the numeral G in Fig. 3) is left free andexposed to contact only with the air in the drying-space, so as to drythe ink before it reaches the wrapping mechanism, and a third length isreceiving the imprint of the printing mechanism.

The length of webbing fed beneath the knife g at each operation of thefeed-rolls ff may be varied by adjusting a wrist-pin f, mounted on aplate f 9, toward or from the center or shaftfw, on which said platerotates, the wrist-pin actuating the oscillatory arm f5 and serving tothrow the rack fla greater or less distance, according to theadjustmentof said wrist pin. When this adjustment is made to vary thelength of the severed strap, the printing mechanism is also shifted, soas to bring the impression at the proper place on the webbing, byloosening'the screws o and sliding the base 02, carrying the printingmechanism, along its bed o the required distance and then retighteningthe screws.

To the upper end of the standard o is attached a stationary overhangingimpressionbed 018, having guides o1 at its ends for guiding the webbing,and in bearings 020 on said standard is mounted a plunger or sliding rod021, having at its upper end a type-carrier or socket 022 for thetype-block o23. A block o24 is adj ustabl y secured by screws c25 onsaid plunger and is connected by links 026 to the lower forked end ofthe bell-crank o5. The upper arm of said bell-crank islikewis'e forked,and the two portions of said arm are slotted at their ends and engagedwith the tru unions o28 of an ink-roller 027. y

029 is an ink plate or table receiving an' intermittent rotary motionfrom a ratchet 030,

lattached to its shaft and engaged by a pawl 031, mounted on a rock arm032. The said rock-arm is connected by a link 033 to one end of abell-crank 034, from the other end of which depends a link 035, having aslot occupied by one of the screws 02",' attached to the block o24 andpivoting the link 026. Thus in the latter part of the downward movementof the plunger o21 the stud o25 engages the bottom of the slot in thelink 035 and causes the ink-plate o29 to be rotated one step. Theinkroll o27 in the forward reci procation of the bell-crank o5, as thetype-block 023 descends, passes from the ink-plate o29 over onto thetype-block to ink the type thereon, and after it leaves the ink-plateits trunnions are supported by means of arms or brackets 036, attachedto the top of the standard 0' and having horizontal portions for thesupport of said ink-roller trunnions. The ink-roll is held down againstthe ink-plate and against said guides by means of springs 037, attachedto its trunnions and to the side forks of the lever 05.

The core of the roll h', from which the paper covering-strip is unwonnd,has its trunnions supported in arms h2, attached to the rear of theframe a, and secured to said arms by means of screws h3 h3 are twoupright guide-rods h4 h4, projecting above the top Of the roll andserving as guides for a markerbar h5, having its ends recessed, as ath6, Fig.

IOO

IIO

l, to engage the rods. Near one end the b ar h5 is provided with apencil-socket 71,7, in which is mounted a marking-pencil h8,the samebeing held in place by means of a thumb-screw hg, and at or near themiddle of the bar is a weight h1", adj ustably held in place by asetscrew k12. At the other end of the bar is a blunt pin orevening-point h13 for holding the marker-bar level above the roll h',the point of the pencil h8 projecting below the bar asubstantially-equal distance with said pin. It will be seen that as thepaper strip is fed and the roll h revolved the pencil hs of the markerwill make a continuous line or mark near one edge of the strip, thismark being on the under side of the strip as it leaves the roll, andhence on the outside of the cover of each of the finished boot-straps.The marker rests by gravity on the paper-roll and descends as thediameter of the roll decreases. It is also readily removable from itsguides and maybe putin place in a reverse position from that shown inFig. l, with the pencil at the left, so as to make a mark on the leftedge of the paper instead of the right. cover of each of the finishedstraps will therefore have a mark on one end of it. The object of thismark is to determine which side of the doubled boot-strap is to beplaced innermost in the shoe. The woven or printed matter on the strapis usuallycovered up by t-he paper sheath or cover, so as not to bevisible, and it is necessary to have some means for determining on whichside or in which direction this matter reads. The improved marker isplaced so that-this mark will be on the ornamented side or end of theboot-strap and may be reversed, as stated, to correspond with the way inwhich the ornamented webbing is fed tothe machine.

It will be noted in Fig. l that the guiderods h4 are placed close to thepaper-roll h', thereby keeping the paper strip as it unrolls inalinement and guiding it straight to the folding mechanism. Afterleaving the roll h the paper covering-strip h passes between twofeed-rolls p p', the lower roll p being intermittently driven throughthe medium of a gear p2 on` lits shaft, an idler-gear p3 on a stud onthe side of the machine, and a mutilated gear p4, attached to the mainshaft c and rotating continuously therewith. In order to prevent motionof the feed-rolls by pulling of the paper or otherwise when themutilated gear p4 is out of engagement with the idler-gear p, I providea brake consisting, as here shown, of a brake-shoe p5, of leather orother suitable material, carried at the end of an arm p6, which' ispivoted on a stud p7 on one of the side frames of the machine, said armhaving attached to it a spring p8, which cooperates with a fixed stud p9in pressing the brake against the periphery of the feed-roll p. rlheupper or presser roll p',

consisting of two sections mounted on a shaft p10 and pressing againstroughened portions of the lower roll p, is provided with an ad- The A justment comprising a spring-arm p12, carrying and journaling the shaftp10 and afxed bya screw p13 to a portion of the frame a, and athumb-screw p14, screwing through an arm or support p15, which isattached to the machine-frame and engaged atits lower end with thespring-arm cl2. The screw p14 is positively engaged with the saidspring-arm, as shown in Fig. 12, the end of the screw passing through ahole in a collar p16, which is bent over and around the edges of thespringarm p12, the end of thescrew being headed up below said collar andabutting against the upper surface of the spring-arm. The thumbscrew p14may be adjusted to give any desired pressure of the roll p againstthepaper strip and when adjusted may be locked in place by means of alock-nut p17. The presser-roll may also be lifted entirely clear of thefeedroll at any time when it is desired to insert or remove the end ofthe covering-strip h to position the same in the feed.

In Figs. 4 and ll is shown an improved guide for facilitating thepassage of the covering-strip beneath the former e, the said guide, ashere shown, consisting of a block or stud e2, secured to the end of aspring-arm e3, which is ,attached to the bottom of the folding-bed a3and projecting upthrough an aperature CL4 in said bed above the bottomof f the groove a2, into which the former e descends. This stud e2 isrounded, as shown in Fig. 4, so as to guide the advancing edge of thecovering-strip h over its upper edge and below the former e, the guidepreventing said strip from being obstructed by the edge of the groove a2or the folder 7c'. When the former e descends, the guide c2 is displacedor depressedthereby against the tension of the spring e3. After thepaper strip has passed under the former e a small quantity of adhesivematerial is deposited on its edge by means ofthe paster t'. The'latteris actuated by suitable arms connected with the rockshaft o14 and visfirst retracted into contact with a paste-lifter i', which takes pastefrom a vat or reservoir ft2. The paster ris then moved forward over thefolding-bed and deposits the paste which it has collected upon the edgeof the covering-strip. The paster, as here represented, consists of awire rod attached to the ends of arms 3, and, as shown in Figs. l and 4,it consists of two alined straight portions2 2 and an u pwardly-bcntmiddle portion 3, which latter does not come into contact with the edgeof the paper. The object of this construction is to paste the edges ofthe cover on both sides of the middle, but to leave the middle portion,where the crease or fold is made in forcing the covered strap throughthe doubling-rolls m5, unpasted. A cleaner and firmer crease istherebymade than when the adhesive material extends over the wholelength of the cover. The reservoir 2, as shown in Fig. 4, is supportedbya bracket i4, attached to the frame a, and has a screwthreaded stem orstud projecting down- IOO IIO

wardly from its bottom and occupying an open-ended slot 'i6 in thebracket 4. The paste-reservoir is locked to said bracket by athumb-screw t7 underneath the bracket, engaging the stem 5. The arm 8,carryinglthe paste-lifter i', is pivoted between ears 12g/9 on the frontedge of the paste-reservoir i2, the saideais and the arm ILS beingapertured to receive a removable split pivot-pin fil. By taking out thesaid split pin, removing the paste-lifter arm s from between the earsfig, and loosening the thumb-nut 7 the paste-reservoir 'i2 may bereadily removed and cleaned or refilled. After the edge of thecover-strip has been pasted and the former e has descended to clamp thestrip beneath the webbing the knife j rises to sever the paper, and thefolding-plates 7c la' approach and wrap the severed portion of thecover-strip over the upper surface of the former e, the pasted edgebeing on top. In order to set the paste and prevent the edges of thecover from separating when the folding-plates are retracted, I provide apresser which presses the pasted edges together and holds them for sometimeV in close contact. q represents the said presser, thesameconsisting of a bar ot' yielding material, such as india-rubber, held ina socket or head q at the end of an arm q2. The latter is attached to arock-shaft g3, mounted in bearings on the machine-frame and havingattached to its end an arm or crank g4, connected by a link Q5 with alever q, pivoted on the stud or shaft b' of the driving-pulley b. Thelever Q6 carries a stud Q7, engaged by a path-cam qs, which is cut inthe inner face of the gear c. As said gear revolves the rockshaft Q3, isoscillated at the proper time, and the presser q descends and pressesupon the folded edges of the paper cover, while the former e isdepressed. The presser then resumes an elevated position, as shown inthe drawings,th'e former@ rises, and subsequently the feed-rolls f f areset in motion to withdraw the webbing or strap and its sheath from olfthe former and advance them under the knife g into the trough or guidem.

The intermeshing gears f2 f3 on the shafts of the feed-rolls ff areplaced closely adjacent to said rolls, inside of the standards whichsupport the rolls, as shown in Fig. 4,

12, Figs. 4 and 1l, attachinfr the same by a screw f13 to the top of thefolding-bed at one side of the feed-rolls and bending its end aroundparallel to the path of the webbing, said end being curved to closelyfollow the contour of the rolls j ust inside the gears thereon. Byinspecting Figs. 4 and 11 it can be seen. that the upper feed-roll f isdeeply iluted or grooved longitudinally, as at f, and between thegrooves the peripheral or traetive portions of the roll are knurled orotherwise roughened to carry the webbing. The object of these recessesin the upper feed-roll is to provide a place for the lodgment of theesicess paste which may eXude from between the pasted edges of the coveras the latter passes between the rolls, and thereby prevent the foulingof the whole surface of the upper roll, which is apt to occur when thesaid surface is left unbroken or merely roughened. The upper feed-rollfis mounted in movable bearings fm, one of which is shown in Fig; ll, andthese bearings are pnt under adjustable spring tension to vary the'pressure between the rolls, the adjustment comprising a cross-bar oryoke f1, placed above the bearing-blocks and having anupwardly-projecting guiding-stem f1?, a spiral spring fm,surroundingsaid stem, and an adjusting-screw f 19, threaded into asocket in a yoke f2, spanning the upper ends of the standards whichsupport the feed-rolls, said adjusting-screw having a lock-nut f21 andits lower end abutting against the spring fw.

As seen in Fig. 8, one of the doubling-rolls' m5 is mounted in bearingsin a movable yoke or rbracket m9, which slides in'slots in the portiona4 of the machine-frame supporting the said doubling-rolls, and anadjustment for varying the pressure between the doubling-rolls isprovided, said adjustment comprising a bow-.spring m10, attached to theback of the bearing or yoke m9, and a screw m12, adapted to be adjustedto bear with different pressures against the spring m19, said screwbeing mounted in a cross-piece m13, which is attached by screws m14 m14to the aforesaid side plates or portions a4 of the machineframe, whichsupport the doubling-rolls m5. The screws m14 also serve to attach tothe part a4 of the machine-frame a paste vat or reservoir r, which islocated below the level of the guide or trough m, just beyond the end ofthe latter, and is carried on an arm r whose :inner end is forked toform the ears r2 r2, slotted at r3 to receive the screws m14. Thevreservoir r has on its rear edge a bearing r4 for a rock-shaft r, andto the ends of said rock-shaft are secured two short arms or cranks r677, set at different angles and pivotally connected to rods?15S r9,sliding in oscillatory apertured blocks 'rm lrlwhich are pivoted onopposite s'ides of the reservoir' r. At the rear end of the rock-shaftT5 is secured a toothed pinion rw, engaged by a gear-segment T14, formedatthe end of a lever T15, which is fulcrumed on the rock-shaftms. Thelever carries at its opposite end an antifriction-roll r, which is heldby a spring rm against the edge of a cam r1. It will be noted byreference to Figs G and 7 that the cani plate or disk rfhas also cnt inits face a cam-groove r2", occupied by a roll m15 on an arm or leverm16. The latter is connected by a link m17 with an arm m18, mounted onthe end of the rock-shaftms, so that the revolution of the disk r1causes the doubling-blade m6 to be reciprocated. The cam-plate lr19 isrevolved by means of a bevelgear c2, secured to the end of the mainshaft o, an intermediate gear c3, meshing therewith,

IOO

IIO

IZO

and a gear on the shaft of the cam-disk meshing with said intermediategear. At the inner end of the rod TS is attached a paster T21, of crownform, hollowed on its under side and having teeth or serrations T22around its edge. The stem T23 of the paster T21 occupies a hole orsocket bored longitudinally in the end of the rod T2, and the end ofsaid rod is screw-threaded and split longitudinally at T24 to give thesides of the socket springiness. The threaded and split end of the rodis slightly tapered and is engaged by a nut T25, which upon beingscrewed onto the rod pinches the split end thereof against the stem T22of the paster, whereby said paster is adjustably secured to the rod andis adapted to be extended or retracted with respect thereto. The end ofthe rod T2 is looped or. bent upwardly and downwardly at T26, so as topass inside of the reservoir T, and at its end is attached a flat plateor paste-lifter T27. The operation of the pasting device is as follows:The paste vat or reservoir T being partially filled with a suitableadhesive paste or cement, the paste-lifter T27, by the operation of itsactuating mechanism, lifts a quantity of paste from the reservoir T intocontact with the paster T21, as shown in Figs. l and 6. This position ofthe parts is assumed before the feed-rolls f f advance the covered endof the webbing into the trough or guide m. As soon as a length ofcovered strap or webbing has been fed into the guide m and thefeed-rolls come to rest the low portion or recess on the edge of the camT12 comes beneath the roll T17, the spring T12 depresses theinner end ofthe lever T15, and the gear-segment T14 on the outer end of said leverrevolves the pinion T12 and oscillates the rockshaft T5. The parts thenassume the positions shown in Fig. 7, the paster T21 being projectedinto the guide or trough m and depositing a drop of paste or cementwhich it has taken from the paste-lifter T27 upon the end of the strapor webbing. The pastelifter T27 meanwhile descends into the reservoir Tto obtain a fresh supply of adhesive material, and as the high part ofthe cam T19 comes under the roll T17 the lever T15 and the rock-shaft T5and its attached parts are again oscillated and the paster T21retracted, the parts resuming the positions shown in Figsf l and 6. Thelength of strap having been severed and the cover positioned by thegages m', the doubling-blade m6 then descends and forces thev severedportion between the rolls m2. The latter fold the strap, and as thestrap passes down between them its ends are pressed together and areheld together by the cement which has been deposited thereon. It will benoted that by merely loosening the screws m14, which attach thepaste-reservoir T to the machine-frame, said reservoir and the partssupported thereby may readily be removed and cleaned or reiilled, thisbeing accomplished without disturbing other parts of the mechanism.

The gages m m are operated by means of a trip-arm m12, attached to therock-shaft m8. Said arm, which is shown in detail in Fig. 10, carries atits upper end a latch m20, pivoted on a pin m21. The end face 4 of thelatch is abrupt, whileits top face or edge 5 is gradually inclined orbeveled. The latch is normally projected by means of a spring m22,attached to the arm 'm12 and engaging the heel m22 of said latch. Vhenthe rock-shaft m2 is oscillated to depress the doubling-.blade 'm6, thearm m12 moves inwardly and its latch m20 engages apin m24 on the heel ofthe arm m12. -The gage-arms m' are thereby brought to a verticalposition to engage the ends of the cover on the severed strap orwebbing, after which as the shaft 'm2 continues to move lto complete thestroke of the blade m6 the pin m21is released from the latch m20 and thegages m' are suddenly returned to their initial' position by means of aspring m25, attached to the arm m2. The return movement of the gages islimited bya stop m26. When the trip-arm m12 returns, the pin m24 engagesthe inclined upper face 5 of the latch m20 and depresses said latchuntil the latter passes the pin, when the latch snaps back to its normalposition.
